IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 216,542, dated J une17, 1879; application filed April 3, 1879.

To all whom it may concern.-

Be it known that I, J osnrrr TRENT, of New York city, in the county andState of New York, have invented certain new and useful Improvements inBurners for Kerosene-Lamps, whichimprovements are fully setforth in thefollowing specification and accompanying drawings, in which- Figure 1 isa vertical section of my improved burner, showing the chimney inposition. Fig. 2 is a top view of the inner guard. Fig. 3 is a sectionof the burner on a line which divides the chimney-holding catchlongitudinally. Fig. 4 is a perspective view of outer cone, of ordinaryconstruction; and Fig. 5, a like view of the inner cone or'fiame-guard.

My invention relates to the peculiarly-constructed inner cone and acatch for holding the chimney in place.

My improved guard has two sides,B, which converge until they reach theflame-slot, thus causing the air to impinge against the side of theflame and feed it with oxygen at that point, while the other two sides,A, are vertical or straight, and carry the air along the edge of theflame, thereby shaping it to the chimney, and feeding it with oxygen ata point higher than by the guards ordinarily used. This, however, isdone without positively deflecting the air into the flame at its edges,as would be the case with the curved overhanging surfaces of the doublecone or deflector which has sometimes been used.

To the plate upon which rests the cone is attached a spring-catch, E, ofthe construction shown. This catch is bent into a V shape, and normallystands out from the chimney; but a slide is attached to the inner arm ofthe V by a lug Working in a slot, and is made to pass over the outer armof the V, which projects above the chimney-gallery, and is there curvedto conform to the chimney; and this slide, when raised, draws the twoarms together, and presses the rounded part against the chimney andholds it firmly in position.

I claim- 1. In combination with the slotted deflector and the wick-tube,the guard having the converging sides B, opposite the sides of the tube,

and the straight sides A, opposite the edges of the tube, substantiallyas and for the purposes set forth.

2. The catch E and slide F, combined in a lamp-burner, as and for thepurpose set forth.
